I wish to connect the DCU3 (Display Controller Unit) of the MPC5645S to a 18 bit TFT display.
In my opinion, the appropriate way to do that is to connect only the 6 most significant bits of the DCU3 to the LCD panel.
This needs to be done for each of the three colors.
I have not been able to find out which is the most significant bit though.
For the red color, is it DCU_R0 or DCU_R7?
In other terms, do I have to connect PA0[DCU_R0] to PA5[DCU_R5] or PA7[DCU_R7] to PA2[DCU_R2] to my TFT ?
